Xcode 7 error: could not read CFBundleIdentifier from Info.plist (null)

Getting this Error as below:

error: could not read CFBundleIdentifier from Info.plist (null)

When I opened Xcode 7, it asked to update app to recommended settings, I did so and then ran the project and received the above error.
I haven't changed anything in the project.
What do I need to change here?
